Remark
F 23 23 MOT STALL
Motor stalled
While starting the motor the current exceeded
the value of parameter
[P 28.17] for a time
longer than parameter
[P 28.15] and the
speed feedback value was below parameter
[P 28.16].
Check: - Motor stalled?
- Load changed during start?
- Correct field current?
- Current/torque limitation;
- Parameter settings
[P 15.08].

F 28
28 ARM OVOLT
Armature (DC circuit) overvoltage
Check: - Setting of param. [P 28.22] suitable
for the system configuration?
- Setting of field current and actual
value as well as the complete
field supply (FIELD EXCITER);
- Was the motor accelerated by
the load?
- Speed scaling;
- Armature voltage feedback;
- Connections between SDCS-
CON-2 and SDCS-PIN boards;
- Coding of voltage evaluation on
SDCS-PIN-xx board.

F 29
29 MAIN UVLT
Mains supply undervoltage (AC); setting via
parameters
[P 40.01] or/ and [P 40.02]
Check: - Is the mains voltage within the
admissible tolerance?
- Did the mains contactor close
and open?
- Voltage scaling via parameter
[P 42.06] rated line voltage
correct?
- Connections between SDCS-
CON-2 and SDCS-PIN-xx boards;
- Coding of voltage measurement
on SDCS-PIN-xx board.
